WILLIAM S. AULT, OF WILLSHIRE, OIIIO.

LAMP-BURNER FOR INCUBATORS.

.To all whom it may concern:

Be it known that I, VILLIAM S. AULT, a citizen of the United States, residing at Villshire, in the county of Van ert and State of Ohio, have invented new and useful Improvements in Lamp Burners for Incubatore, of which the following is a specication.

This invention relates to automatic lamp burners :tor use in connection with incubators, the object of the invention being to provide simple and reliable means influenced by the temperature Within the incubator for automatically raising and lowering the wick of the lamp and thereby correspondingly increasing or diminishing the heat, thus enabling an equal temperature to be maintained in the incubating chamber at all times.

With the above general object in view, the invention consists in the novel construction, combination and arrangement of parts hereinater fully described, illustrated and claimed.

In the accompanying drawings Figure l is a vertical longitudinal section through an incubator showing a lamp thereon and operating mechanism for the wick of said lamp embodying the present invention. Fig. 2 is a vertical diametrical section through the burner. Fig. 3 is a similar section taken at right angles to Fig. 2. Fig. I is a detail perspective view of the fork and lever at the upper end of the stem of the thermostat. Fig. 5 is a detail perspective view of the tubular wick carrier. Fig. 6 is a detail perspective of the wick adjusting device. Fig. 7 is a detail view of the bearing member of the wick adjusting device.

Referring to the drawing, l designates the heating chamber of an incubator of any desired construction and 2. the compartment in which the lamp 3 is located. In carrying out the present invention, the tubular wick holder 4 is mounted to slide up and down within the wick tube 5 of the burner as indicated in Figs. 2 and 3 and is provided with a bearing 6 in which is journaled a wick shaft 7 having one or more star Wheels S which Work through vertical slots 9 in the wick holder 4, as indicated in Figs. l and 3.

Projecting from the bearing 6 is an eye 10 Specification of Letters Patent.

receiving one end of a lever 11 which is fulcrumed at l2 on a bracket connected with the trame of the burner, the other end ot' said lever being provided with a suitable counterbalanee weight 123, and a hook or eye 11i to which is connected a chain 15 or other flexible connection which extends upward and is attached to one end ot a superimposed lever It, the said lever being journaled on a :tulcrum pin 17 which is carried by a fork IS on the upper end of a rod or stem I9. The rod or stem 19 extends downward through a tube Q() mounted within the incubator and provided at its lower end with a raised or supporting bracket 2l upon which is mounted a thermostat 9.2 to which the rod or stem 1S) is connected.

23 designates a balance weight which is adjustable on the lever 1G to give the proper poise to the connections which control the operations of the wick carrier 4L.

It will be understood in view oit the foregoing description that when the temperature within the incubator becomes too high, the thermostat 22 will expand accordingly and move the stem 19 upward thereby raising the lever 1G and operating the lever ll. through the connection 15 thus depressing the wick carrier 4l and lowering the wick and tlame. This reduces the heat generating power oi the lamp and as the temperature within the incubator' increases the thermostatontraets thereby lowering the ulcrum pin 17 of the upper lever 16 and through the connections described operating the lever ll and again raising the wick. It will thus be seen that the device is entirely automatic after once lighting the lamp. The automatic wick controlling connections, are independent ot' the usual wick adjusting device and the latter may be operated and set by hand without intertering with the automatic part of the apparatus.

Having thus described the invention, what is claimed as new, is H A heat regulator for incubators comprising a lamp burner, a stationary wick tube, a tubular wick carrier movable relatively to the upper end oit the stationary wick tube and within the same, a thermostat located within the incubating chamber, operating Connections between said thermostat and wick-adnstno* 'shaft 'ournaedv on and car! wick Carrier whereby changes in the telnperfied by Said wick carrier. 10 ature of the neubatol1 ehambel` will auto- In testimony whereof I ax my signature lnatoally eeet a sliding movement of the in presence of two witnesses.
